Rita, ha, ha, ha...
If couldn't be backtested than couldn't be backtested, period! Then backtesting gives a false results.
Rita claim big wins with it. Only forward demo test will tell us who is winner.
I don't believe in backtesting, anyway! Backtesting is the same as witchcraft.
Forex market is ever changing by manipulation and backtesting cannot recognize manipulations (market makers, specialists, brokers, financial corporations etc.) Grow up and test forwards. Only realistic testing is with live micro account! Even demo is not reliable.
A few times I had a good results on demo (EAs) and barbecued live account with it.
Trading is like playing Chess, they do move, we do move and somebody gets checkmate! All about tactical maneuvers.
